Common Issues with Gas Furnaces and the Fix

San Jose Area: Not having heat when it is cold is never convenient, but if you have children or older people in your home it can become a more urgent situation - even in the temperate Silicon Valley.

More times than not the solution to your heating problem is just a click or a battery change away. No need to call and pay for a professional heating expert before you rule out the more common issues. In the colder weather, heating companies receive more calls which means that you may be waiting for service. Try these tips and maybe you will have heat in a snap.

Sometimes a battery operated thermostat has old or dead batteries. If your thermostat is battery operated, try replacing the batteries, one indication of a battery issue is a weak or missing display.

Check if the thermostat is set higher than the current temperature (so it is asking the furnace for heat). If the setting is below the current temperature the furnace will not go on. Make sure it is not on away mode or if a programmable thermostat make sure that it isn't during a time when heating is not called for; if so override the thermostat by upping the temperature for heat.

If you turn off your heat in the summer or have air conditioning, it is possible that the thermostat is in the wrong mode. Make sure that the thermostat is in heat mode and not in A/C or off modes. Also try moving the temperature lever or dial of the thermostat up and down a couple of degrees to get it to kick on.

Make sure that the switch to furnace (usually located on the wall next to the furnace) is in 'on' position. This switch can be accidently turned off if brushed against or perhaps it was purposely turned off for the summer. Many times this switch looks like a common light switch.

It is possible that the circuit breaker was tripped. Try resetting the circuit breaker. ***A word of caution, if others are troubleshooting the furnace also make sure they are aware that you are turning the power back on to the furnace. If it trips again, it could indicate a serious problem and should be checked into. How to reset a breaker.

If you have a pilot light make sure it is lit. Keep in mind many newer furnaces do not have a constant pilot light.

As always change your filter regularly, it can cause the furnace to also shut down.

If these tips don't work it may indicate a more serious problem - please call Cold Craft, Inc. and our expertly trained NATE Certified Technicians can assist you in getting comfortable again - 408.374.7292.

If someone that is not a trained furnace repair person was attempting to fix the furnace you may want us to check it. Sometimes these fixes include bypassing a safety mechanism that can cause Carbon Monoxide Poisoning or fire.

I hired this company to change our heater. By just talking to the owner I didn’t even bothered calling anyone else. They maybe more or they maybe less than other companies but what was important for me was to get the job done right. Our heater was an older model and they had to do some special modif…

I’ve used Cold Craft a few times now and I have always been happy with their customer service, timeliness and pricing. In one instance I had a furnace emergency late in the afternoon on a Friday. They had someone out to fix the problem the same day though they were quite busy. I don’t usually provid…

I am totally impressed with this company and their professionalism! Last fall Cold Craft came to my house to inspect our furnaces, which were over 23 years old. Our utility bills in the winter were well over $400 and we almost never used the upstairs furnace and used the downstairs furnace frugally.…

I am really happy with this heating and cooling company. I posted another review and Yelp did not post it. I don’t know why but this time I am giving the company 4 stars because i think that this might be posted. These guys came out a few weeks ago and they fixed my furnace and they did a wonderful …

They were very responsive and they returned my call quickly. The two technicians who came out seemed very competent and qualified. They explained what they were doing and they also consulted with the manufacturer to be sure that everything was done properly. They came highly recommended.
